2 Claims.

This invention relates to winding frames. employed for winding spoolsused in therweaving of Axminster rugs.

. The object of the invention isto facilitate the 'y operation of.clamping the strands of ,yarn togetherv after winding and prior tocutting, by the provision of a combination of comb clamp and spool reedof novel construction lwhereby the yarn is guided between the teeth ofthe clamp m, without the danger of splittingthe individual '1^ strandsof yarn by the teeth as has been common heretofore. f l

At I have indicated by novel reed, disposed in proximity to the spool 4.It comprises a plurality of dents 3| extending vertically from a 505'mounting 32 which is supported at both ends by levers 33 which yarepivotally mounted, as will appear, to elevate the reed to itsvdottedline position for clamping up the yarn after the run.

, As indicated in Fig. 9, each of the dents 3| is constructedof a stripof metal of uniform Width and thickness, the bottom portion 31 of thefront edge of which is twisted slightly out of alignment with the upperportion 38 of the front edge.

60 This twisting operation may be performed by f' my invention isprovided, as is customary, with (Cl. .Z8-55.5)

holding securelythe entire rear face 39 of the dent and theny graspingthe lower corner 31 of the front face, after-.which the lower portion isbent to the left-as viewed in Fig. 9 and out of alignment with the upperportion 38 of the front 5 face, without bending either the upper portionof the front face, or the rear face throughout its entire area. n*Afterthe dents are bent in this manner, they are mounted in the supportingblock 32 at equally spaced intervals,parallel with 10. each other andwithmtheir twisted lower portions all curving to the left, as viewed inFig. 4, in

parallel curves. 1

The supporting block 32 has` -secured to: its front face, adjacent, thebases of the dents 3|, by 15 suitable bolts 34, a block 35 which isslotted at 36 to receive a comb member 40 (Figs. 5 and 8) forming oneelement of the usual comb clamp adapted to clamp up the vyarn afterwinding.

The levers 33 supporting the opposite ends of 20 reed 30 are fixed toopposite ends of a rotatably mounted shaft r1| The lever 33 shown inFig. 1 joins pivotally at with one end of a link 46, the other end of..which link is pivoted at 41 to arm 48 WhiChisXed to a shaft 50, suitablymounted to rotate.

As indicated in Fig-.2, shaft 43 mounted adjacent shaft 50 carriesfreely mounted thereon, a cam member which may be in the general shapeof a truncatedcone to provide `a tapering 30 cam surface which,gradually diverges from a low portion 62 closely adjacent `the surfaceof the shaft 43, to a high annular portionf63 formed of `a hub ofsubstantialthickness as compared with the low portion62 of the cam. Thecam 60 y, has lugs 65 depending from the enlarged end thereof. Pivotallysecured tothe bolt 66 passing though the lugs. 65 is one end of` a link10 which is pivoted at its otherend at 12 to a link 13. The link 13 isfixed to stud shaft 14 rotatably mounted in lug 15 depending from andsecured to the frame -of the machineV in any suitable way.

The links 10 yand 13 form a toggle joint actuated byrotation of shaft 14to which link 13 is secured and the toggle is provided with a stop 12aadapted to-abut the surface 12b' when the toggle is straightened and asecond stop 12e which yabuts surface 12d when link 13 is swung to theleft slightly beyond a horizontal position. As indicated in 3, a pinion11, secured to shafty 14, meshes with a rack 18 pivoted at 19 to a 50push-pull rod 80,v which has a sliding bearing in the side framememberl0 of the machine and is provided at its extremity with a handknob 8| by which the rack may be lmoved longitudinally of the shaft 43.

. Riding on the surface of the cam 60 is a cam follower carried by anarm 82 (Fig. 2) fixed to the aforesaid shaft 50 vby one or more bolts93.

v'With `the machine constructed as above dew scribed, its operation isas follows: The winding position of the spool reed is that shown in fulllines in Fig. 1 obtained by disposingthe cam 6U in its `dotted positionof Fig. 2 with stop 12a against surface 12b. Cam follower 90 is now onlower portion 62 of the cam. It will be noted),y

the roll 2 in engagement with roll 3, in amanner from Fig. 4 that theyarn l now passes through the dents 3| of the reed above thelowertwisted portions 31 thereof, in which vposition they strands ofyarn guided by adjacent dents,are given ample space 38A for the runningof the yarn.

Prior to commencing the winding, the comb member 4!) of the clamp issecured in position in the groove 3%* immediately in front of the dentsj 3| lbelow the yarn and in alignment with the bases of the dents. Itwill be observed by a comparison of Figs. 4 and 10, that the partial.twists of the lower front edge portions 3l of the dents form a pluralityof straightline openings for the passage of taut yarn, each of whichopenings is bounded on one side by the front edge portion 3'! of onedent and on the other side by the rear edge 39 of the next adjacent denton the left, as viewed in Figs.l 4 and 10. Thus, as a result of thestraight line position of the yarn under tension, the twisting of thebottom portions of the dents 3i provides, in eiect, a number of areas31A for guiding the yarn at the bottom of the dents which are quitenarrow as compared with the wide areas 38A at the upper portion of thedents.

The clamping comb 40, when properly positioned in the slot 35 providesnarrow spaces 40A, between adjacent teeth, in alignment with the narrowspaces 37A at the base of the dents, with the pointed tips of the combteeth disposed, as-

indicated in Fig. 5, in alignment with the deflected portions 3l of thedents. To insure this position of the comb, the slot 36 may be of xedlength to receive and properly position a comb of corresponding lengthor, if desired, it may be prof vided with adjustable end portions forvarying its length to adjust the position of the comb. At thecompletionof the winding operation,

during which, as stated, the yarn is guided byy spaces 38A as shown inFig. 5, the push rod 80 (Fig. 2) is pushed to the right, as indicated inthat view, to elevate the reed 30 from its full line position of Fig. 1to itsdotted line position, whereby, in effect, to depress the yarn linto the comb of the clamp and between the teeth thereof.

By this movement of the push rod 80 to the right,l

a clockwise rotation of the link i3 is effected until stop 712e abutssurface 12d which moves the link 'it to the left, thereby pushing thelugs 65 and cam Si) to the left to make the cam follower 9e ride fromits lower position at 62 to the elevated position at 63. 'I'his movementof the cam follower elevates the leverl 92 to which it is Secured, toimpart a slight rotation to the shaft 5U. This movement of the shaft 50is imparted to the lever 48 to rotate that lever and the lever 46 (Fig.l) and lever 33 from their full line to their dotted line positions toelevate reed 30 to its dotted line position. As indicated in Fig. 6,this movement in effect causes depression of the taut strands of yarn,first into the narrow passages SIA and thence into the slots A betweenthe teeth of the comb, as indicated at IA, and it willv be observed thatduring this movement the yarn cannot touch the points of the teeth ofthe comb. After this operation, the cap B9 is secured over the comb toclamp the yarn in the usual manner, a small length of yarn is drawn offfrom the creel, the clamp is removed from the slot 36 and the yarn iscut adjacent the clamp. n Y

The operation of drawing off .ar small klength of yarn from the creelmay be effected manually after elevating the upper roll 2, or it may beeffected mechanically by imparting rotation vto j is removed fromthe'setting frame (afterv the top roll 'I hasbeen moved out of the wayin any suitable manner) an empty spool .is inserted in windempty Vspoolandthe winding operation repeated. Prior to the commencement of rotationof the winding rolls, the'reed 30 is dropped frorriitsvr dotted line toits full line position by movement of the push rod 8U to the left, untilstop `lila abuts surface 'IZbto position the link 'iii yasindi-` catedin dotted lines in Fig. 2 and to dispose the yarn as indicatedin Fig. 4.A combfclamp is then inserted;

It will benoted that the dents of the ,spoolA reed Sil by being twistedkat their bases present the narrow straight-line apertures 31A withoutactually diminishing the spaces between adjacent dents at their bases'and I thereby provideample room ,at the base of the reed for the passageofl knots during the operation of drawing oil yarn from the creel afterthe spool has been clamped.

I claim: Y a

l. A yarn guiding reed for use with a clamping comb, the dents of saidreed being spaced ,from

each other tol form a series of apertures of preing position, the yarnends are lapped about the i;

for holding the comb spaces in registry withl said ing the reed and thecomb holder relative fto the yarn to depress the yarn linto said lowerapertures, and yarnjdeflecting means for guiding the yarn past the combteeth and into the' comb spaces during such movement. l

2. In a setting frame, the combination of a yarn guiding reed havingdents spaced to .form a series of apertures of predetermined width alongthe upper portion of the reed for guiding theyarn during the run of themachine, the lower por-` tions of said dentsbeing deflected out ofalign? ment with the upperportions thereof to form a lower series ofapertures which confine the yarn,`

more narrowly than the upper series,` a yarn clamping comb having teethseparated by'spaces' adapted to register with the lower seriesofapertures, a comb holder xcdly secured to the reed for holding the combspaces in registry with saidlower apertures, and means forsimultaneously moving the reed and the comb holder relative to the yarnto depress the yarn into said lower apertures, the tips of the teeth ofthe comb being aligned with the deected lower portions of the reed dentsso that when the yarn is so depressed it is guided past the tips `of theteeth ofthe comb and into the comb spaces.
